I had multiple issues of *this type* but with amd64, going from 
stable/14 to stable/15. I can't remember them all exactly.

What fixed them all for me was starting afresh with an
empty /usr/obj.

For good measure, I deleted all that was in /var/cache/ccache/*
and then in /usr/src make -j10 cleanworld cleandir clean.

Then the usual make -j10 kernel && reboot then 
make -j10 buildworld etc etc

Maybe this'll work for you. Good luck.
